Narrative
Sandberg bluegrass (P oa secunda J. Presl.) is a cool-season, perennial bunchgrass that matures early in the growing season. This grass is one of the first to green up in the spring, but is cured and dormant by early summer. The plant usually occurs as small tufts, with soft basal leaves and few to many flowering stalks that are naked except for two small leaves. The leaves have the typical bluegrass characteristics of prow-shaped tip and double grooves down the center of the leaf surface.
